2014-04-18 cwRsync 5.3.0

Fixed a failure to remove the partial-transfer temp file when interrupted (and rsync is not saving the partial files).
Changed the chown/group/xattr-set order to avoid losing some security-related xattr info (that would get cleared by a chown).
Fixed a bug in the early daemon protocol where a timeout failed to be honored (e.g. if the remote side fails to send us the initial protocol greeting).
Fixed unintended inclusion of commas in file numbers in the daemon log.
We once again send the ‘f’ sub-flag (of -e) to the server side so it knows that we can handle incremental-recursion directory errors properly in older protocols.
Fixed an issue with too-aggressive keep-alive messages causing a problem for older rsync versions early in the transfer.
Fixed an incorrect message about backup-directory-creation when using –dry-run and the backup dir is not an absolute path.
Fixed a bug where a failed deletion might not affect the exit code.
Fixed a bug that caused a failure when combining –delete-missing-args with –xattrs and/or –acls.
Fixed an itemize bug that affected the combo of –link-dest, -X, and -n.
Fixed a problem with delete messages not appearing in the log file when the user didn’t use –verbose.Improve chunked xattr reading for OS X.
Removed an attempted hard-link xattr optimization that was causing a transfer failure. (If you need to interact with an rsync 3.1.0 using –hard-links & –xattrs, you can specify –protocol=30.)
We now generate a better error if the buffer overflows in do_mknod().Fixed a problem reading more than 16 ACLs on some OSes.
Switched Cygwin back to using socketpair “pipes” to try to speed it up.
Added knowledge of a few new options to rrsync.
Added the support/rsync-no-vanished wrapper script.
Made configure more prominently mention when we failed to find yodl (in case the user wants to be able to generate manpages from *.yo files).

2010-03-01 cwRsync 4.0.3 patch 100

Rsync without socketpairs.
This patch contains an rsync 3.0.7 executable for Cygwin with socketpairs turned off (Pipes are used instead). There are some threads on the net showing that implementation of socketpairs on cygwin 1.7 may be error-prone.

2008-09-07 Cwrsync 2.1.5

Cwrsync 2.1.5 includes rsync 3.0.4 , which is primarily a bug-fix release. The only enhancement is the adding of a way to interact with an overly-restrictive server that refuses rsync’s behind-the-scenes use of the -e option. Notes: cwRsync VERSION 2.1.5 - September 2008 highlights (see changelog for more info) - plain Rsync 3.0.4 - Update package 100 with time-limit and transliteration patches Changes: cwRsync - Rsync client and server for Windows Version 2.1.5 - September 2008 CHANGES FROM VERSION 2.1.4 GENERAL 1.

2008-08-19 Experimental Cwrsync updates with Cygwin 1.7.0

Windows 95, 98 and Me are not supported anymore. The new DLL will not run on any of these systems.
Mount points are no longer stored in the registry. Use /etc/fstab and /etc/fstab.d/$USER instead. Mount points created with mount(1) are only local to the current session and disappear when the last Cygwin process in the session exits.
PATH_MAX is now 4096. Internally, path names can be as long as the underlying OS can handle (32K).
UTF-8 filenames are supported now. So far, this requires to set the environment variable CYGWIN to contain “codepage:utf8”, but this will likely disappear in a few weeks time. The setting of $LANG or $LC_CTYPE will be used instead.
The CYGWIN environment variable options “ntsec” and “smbntsec” have been replaced by the per-mount option “acl”/“noacl”.
Reworked pipe implementation which uses overlapped IO to create more reliable interruptible pipes and fifos.
Reworked pipe handling for better speed and better support for signal processing.
Fallout from the long path names: If the current working directory is longer than 260 bytes, or if the current working directory is a virtual path (like /proc, /cygdrive, //server), don’t call native Win32 programs since they don’t understand these paths.
On the first usage of a DOS path (C:foo, \foobar), the Cygwin DLL emits a scary warning that DOS paths shouldn’t be used. There’s also the new CYGWIN=nodosfilewarning setting to disable that.

2008-07-28 Cwrsync 2.1.4

Release 2.1.4 contains many updates including rsync 3.0.3, OpenSSH 5.1, OpenSSL 0.9.8h and Cygwin 1.5.25-15.

2014-04-18 cwRsync 5.3.0

Fixed a failure to remove the partial-transfer temp file when interrupted (and rsync is not saving the partial files).
Changed the chown/group/xattr-set order to avoid losing some security-related xattr info (that would get cleared by a chown).
Fixed a bug in the early daemon protocol where a timeout failed to be honored (e.g. if the remote side fails to send us the initial protocol greeting).
Fixed unintended inclusion of commas in file numbers in the daemon log.
We once again send the ‘f’ sub-flag (of -e) to the server side so it knows that we can handle incremental-recursion directory errors properly in older protocols.
Fixed an issue with too-aggressive keep-alive messages causing a problem for older rsync versions early in the transfer.
Fixed an incorrect message about backup-directory-creation when using –dry-run and the backup dir is not an absolute path.
Fixed a bug where a failed deletion might not affect the exit code.
Fixed a bug that caused a failure when combining –delete-missing-args with –xattrs and/or –acls.
Fixed an itemize bug that affected the combo of –link-dest, -X, and -n.
Fixed a problem with delete messages not appearing in the log file when the user didn’t use –verbose.Improve chunked xattr reading for OS X.
Removed an attempted hard-link xattr optimization that was causing a transfer failure. (If you need to interact with an rsync 3.1.0 using –hard-links & –xattrs, you can specify –protocol=30.)
We now generate a better error if the buffer overflows in do_mknod().Fixed a problem reading more than 16 ACLs on some OSes.
Switched Cygwin back to using socketpair “pipes” to try to speed it up.
Added knowledge of a few new options to rrsync.
Added the support/rsync-no-vanished wrapper script.
Made configure more prominently mention when we failed to find yodl (in case the user wants to be able to generate manpages from *.yo files).

2010-03-01 cwRsync 4.0.3 patch 100

Rsync without socketpairs.
This patch contains an rsync 3.0.7 executable for Cygwin with socketpairs turned off (Pipes are used instead). There are some threads on the net showing that implementation of socketpairs on cygwin 1.7 may be error-prone.

2008-09-07 Cwrsync 2.1.5

Cwrsync 2.1.5 includes rsync 3.0.4 , which is primarily a bug-fix release. The only enhancement is the adding of a way to interact with an overly-restrictive server that refuses rsync’s behind-the-scenes use of the -e option. Notes: cwRsync VERSION 2.1.5 - September 2008 highlights (see changelog for more info) - plain Rsync 3.0.4 - Update package 100 with time-limit and transliteration patches Changes: cwRsync - Rsync client and server for Windows Version 2.1.5 - September 2008 CHANGES FROM VERSION 2.1.4 GENERAL 1.

2008-08-19 Experimental Cwrsync updates with Cygwin 1.7.0

Windows 95, 98 and Me are not supported anymore. The new DLL will not run on any of these systems.
Mount points are no longer stored in the registry. Use /etc/fstab and /etc/fstab.d/$USER instead. Mount points created with mount(1) are only local to the current session and disappear when the last Cygwin process in the session exits.
PATH_MAX is now 4096. Internally, path names can be as long as the underlying OS can handle (32K).
UTF-8 filenames are supported now. So far, this requires to set the environment variable CYGWIN to contain “codepage:utf8”, but this will likely disappear in a few weeks time. The setting of $LANG or $LC_CTYPE will be used instead.
The CYGWIN environment variable options “ntsec” and “smbntsec” have been replaced by the per-mount option “acl”/“noacl”.
Reworked pipe implementation which uses overlapped IO to create more reliable interruptible pipes and fifos.
Reworked pipe handling for better speed and better support for signal processing.
Fallout from the long path names: If the current working directory is longer than 260 bytes, or if the current working directory is a virtual path (like /proc, /cygdrive, //server), don’t call native Win32 programs since they don’t understand these paths.
On the first usage of a DOS path (C:foo, \foobar), the Cygwin DLL emits a scary warning that DOS paths shouldn’t be used. There’s also the new CYGWIN=nodosfilewarning setting to disable that.

2008-07-28 Cwrsync 2.1.4

Release 2.1.4 contains many updates including rsync 3.0.3, OpenSSH 5.1, OpenSSL 0.9.8h and Cygwin 1.5.25-15.

By enabling the jail copssh in the jail.local file, you will be able to enhance your Copssh installation with a brute-force protection system. See our FAQ for instructions.
